Abstract

L'invention porte sur un circuit de sang qui permet de réaliser l'amorçage pour une opération sûre de façon automatique. De façon spécifique, l'invention porte sur un circuit de sang pour purifier un sang à travers un filtre (56). Ce circuit comprend : un conduit de retrait de sang qui est relié à l'entrée du filtre (56) à l'une de ses extrémités et est composée d'un premier conduit de retrait de sang (84), un second conduit de retrait de sang (88) et un troisième conduit de retrait de sang (89) ; un conduit de retour de sang qui est relié à la sortie du filtre (56) à l'une de ses extrémités et qui est composé d'un premier conduit de retour de sang (92) et d'un second conduit de retour de sang (94) ; et un conduit (dérivation) anti-coagulant (90) pour diminuer la différence entre la pression de la solution d'amorçage s'écoulant à travers le conduit de retrait de sang et la pression de la solution d'amorçage s'écoulant à travers le conduit de retour de sang.
